So there were maJOR reasons why this Dash Doll was fah-reaking out about her milestone birthday last week!

At a special event in NJ on Monday, Khloe opened up about her age, and everything she must leave behind:

"I was really freaking out to turn 30. I think everyone does. Kim did, I don't remember if Kourtney did or not. I was really freaking out and I would not accept it and I think I'm slowly like, you know, let's put the 20s behind me and there were some good years and some not so good years so let's hopefully have the 30s be all good years. Everyone says that the 30s you get this different sense of confidence and you lose all of your insecurities."

In July, father John McCain was diagnosed with stage 4 glioblastoma, an aggressive form of brain cancer, which also claimed Beau's life.

When the 33-year-old began crying, the politician went over and consoled her, adding:

"There is hope... And if anybody can make it, your dad [can]."

Biden is also optimistic about "breakthroughs that are occurring now," regarding potential treatment options and cures.

"There's a lot of things happening. Any of you who have somebody who is diagnosed with gliobastoma, which is about as bad as it gets, there's breakthroughs that are occurring now... And it can happen tomorrow."
